For the chokeberry-apple jam, remove the stems from the chokeberries and wash them, peel and cut the apples. Mix everything with the jelling sugar and bourbon vanilla and leave to infuse for 1 – 2 hours.
Boil on high for about 5 minutes and blend with a hand blender. Then bring to a boil again and let simmer for 3 minutes. Pour into jars and allow to gel.
